Gorgeous, 7.7" Tall Iridescent Ammonite Cluster - Russia

This is a gorgeous cluster of Deshayesites & Aconeceras ammonites from the Lower Cretaceous deposits of the Volga River in Russia. It has been beautifully prepared from the hard concretion from which it was found. The ammonites have a wonderful iridescent shell preservation. The largest ammonite is 2.25" wide and the entire piece is 7.7" tall. The base of the rock has been cut flat so that it stands up nicely on a flat surface without the need for a display stand.

It comes with an acrylic display stand.

Ammonites were predatory cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
